C section post op

I’m 3 weeks post op from an emergency c section.

Everything has been going great, had my incision looked at last week and was told it’s healing nicely.

So, today I bent down just a little further than I was used to, to pick my 6 pound baby up from his swing. I then felt a bunch of pulls and pops. Now I’m in an excruciating amount of pain that pain killers are barely touching. I can’t hold my baby on my belly at all because it hurts way too much.

Should I go to the ER or wait until morning to call my OB?
